how to use net memory profiler

In the past, we had to use win32 API to obtain information such as CPU and memory. But now, the. NET FrameWork has encapsulated these Apis into the. NET class library, so we can easily obtain this information using the. NET class library. First, we will introduce several cla

. NET performance analysis best practices: how to find out. Net with too much memoryCode(Basics) One of the factors that often affect the performance of. NET applications is that the Code consumes too much memory. Many developers often do not pay attention to performance when writing code, so that the applicationProg

-generation object is collected after startup. # Gen 1 collections: the number of times a generation 1 object has been collected since the program was started. # Gen 2 collections: the number of times a 2-generation object has been collected since the program was started. CLR profiler CLR profiler is a free tool for Microsoft to display program memory

IntroductionAs one. NET programmer, we know that the memory management of managed code is automatic. NET can ensure that our managed program at the end of all release, which for our programmers save a lot of trouble, we can not even think how to manage memory, anyway. NET it

In use. NET, it may run into memory overflow, or the memory footprint is too large when the program is running. In particular, the hospital PACs, RIS system for the picture operation is more frequent, the program memory control is particularly important, this time can be use

In. net, no matter which type of variable occupies a space in the memory. Int, datetime, float, and other basic data types store actual data in the corresponding memory space, while the referenced variables are different, the memory space occupied by the referenced variable is not the actual object data, but the addres

During the WindowsCE development process, the device may easily report the error "insufficient memory" during the running process, and then it will crash. The memory of my current device is 64 MB in total. After the CE system is started, it will occupy part of the memory. The program has fewer available memory. The f

GC executes by marking objects in these references, clearing unmarked objects to complete memory release (tagging, Cleanup algorithms), and, of course, purging may be step-by-step (such as transferring Finalize queues, etc.). Due to performance considerations such as marking, the interrupt time of the cleanup algorithm, the
